As if the Miami Dolphins did not have enough issues to deal with because of injuries to Mike Pouncey and Knowshon Moreno, The Dolphins announced Thursday that Jordan has been suspended without pay for the first four games of the regular season for violating the NFL's policy on performance-enhancing substances.

Jordan’s rookie season was less than spectacular, dealing with injury and lack of playing time. This season, the defensive end came to camp bigger and stronger, and Jordan looked like he would have a bigger role in the Dolphins’ defensive scheme.

"We were disappointed to learn about Dion's suspension," Dolphins coach Joe Philbin said in a statement released by the team, which is part of a story on "Dion has accepted responsibility for his actions and is committed to improving, both on and off the field, in preparation for the upcoming year."

Jordan -- the No. 3 overall pick in the 2013 draft -- also released a statement through the team.

"I recently learned from the NFL that I tested positive for stimulants that are banned under the NFL policy," the statement read. "I worked carefully with my advisors and the union to investigate the test results, and I take full responsibility for the test results.

"I'm very sorry for the impact of this situation on my teammates, coaches, Stephen Ross, the entire Dolphins organization, fans and my family as well. I will continue to work extremely hard during training camp and preseason. During the suspension, I will stay in top shape and will be ready to contribute upon my return."

The Dolphins shocked everyone in the NFL last season when it traded up from the 12th position in the draft to 3rd. The organization’s biggest need was on the offensive line at tackle, but chose the Oregon junior instead.

Jordan is eligible to return to the Dolphins' active roster on Sept. 29 following the team's Week 4 game against the Oakland Raiders. The Dolphins have a bye in Week 5.

The suspension comes after Jordan showed up at Dolphins OTAs with nearly 20 pounds of added muscle to his frame. The 6-foot-6 Jordan had a part-time role as rookie playing at 248 pounds. Armando Salguero of The Miami Herald noted at OTAs that Jordan looked "as if he took an air pump" to his arms and shoulders.
